Rainbowfish Suggestions

0

I have a 29 gallon tank and I am contemplating getting a strictly rainbowfish aquarium.

I know I can't have many (if any) of the bigger rainbows like M. boesemani or Turquoise. But I know I can have some neon rainbows, but is there any other type that could work too?
But can you guys give me some suggestions of many a mix that I could add and not be overstocked? Or is getting Rainbowfish for this size aquarium just a horrible idea? I am open to any ideas!

MacCulloch's Rainbow( Melanotaenia maccullochi) only reaches about 2 1/2 inches, they are relatively drab compared to other rainbows, but they were among the first to be imported. They have pink-olive scattered on their sides. I haven't seen any in LFS though.

Threadfin rainbows (Iriatherina werneri) reach about 2in and are pretty skinny, they are durable and are relatively adaptable to water conditions. They look really good when put with other colorful tetras and such.

Another is the Celebes Rainbowfish( Marosatherina ladigesi) which is another slim body rainbowfish that reaches less than 3 in. They do well in peaceful settings, and remind one of a more active bigger, colorful version of a silvertip tetra.

There are numerous Melanotaenia that are infrequently reported that reach a small size that are suitable for that tank.

Al these require regular rainbowfish care and should do fine in a 29 gal. Choose tankmates with care, and good luck hope you can track some of these down.

With your tank size, I would stick with the blue eyes. Rainbows like to be in schools and are strong swimmers. I had some in my 55 gallon and found my tank too small for them. They would need the 6 ft length tank to be happy, I think.

Or simply stock a large school of the neon rainbow. They're the size of a large tetra.
